Net worth is assets minus liabilities at a point in time. The hard part is not subtraction - it is deciding what counts as an asset, which balances are gross of fees, and whether you mark illiquid positions to market or to conservative estimates.
Five-minute capture buckets
- Cash & equivalents: checking, savings, money market, stablecoins you treat as cash (note tax).
- Investments: brokerage balances, retirement accounts, RSUs vested and sellable.
- Property: fair value minus mortgages/HELOCs - use conservative comps if you will not sell soon.
- Other assets: vehicles, private loans receivable, business equity if separately trackable.
- Liabilities: credit cards, student loans, tax payable, personal guarantees counted only if real.
Why monthly snapshots beat obsessive daily checks
Net worth volatility is normal when markets move. A monthly cadence smooths noise while still catching drift in spending, debt paydown, or forgotten subscriptions. Pair the number with a one-line narrative (“market beta + paid car loan”) so future-you understands the delta. Browse finance tools for loan and savings calculators that feed the same spreadsheet.
